Nickel-base superalloys are the most complex and the most widely used for high temperature applications such as aircraft engine components. The desirable properties of nickel-base superalloys at high temperatures are tensile strength, thermomechanical fatigue resistance, low thermal expansion, as well as oxidation resistance. At elevated temperature, fatigue cracks are often initiated by grain boundary oxidation, and fatigue cracks often propagate along grain boundaries, where the oxidation...

New flight test techniques in use at Ames Dryden are reviewed. The use of the pilot in combination with ground and airborne computational capabilities to maximize data return is discussed, including the remotely piloted research vehicle technique for high-risk testing, the remotely augmented vehicle technique for handling qualities research, and use of ground computed flight director information to fly unique profiles such as constant Reynolds number profiles through the transonic flight...

A study was made of the perceived success or failure of early field experiences prior to student teaching as perceived by cooperating teachers (CT) and field experience students (FES). Subjects were secondary school teacher education majors (n=145) and their cooperating teachers (n=34). Measures were taken of expectations, problems, and values over a period of nearly two years. Questions directed to the CTs concerned expectations they brought to the experience, problems they incurred in dealing...

This paper reports the results of a study of the implementation of multicultural education policy initiatives in Australia. An outline of the study's methods follows brief discussions of the emergence of multicultural education as a policy issue and the context of multicultural education in Australia. To assess the impact of multicultural education in the state of Western Australia, a federally funded small-scale grants scheme was selected as the study's focus. All grantees receiving such funds...

A model for the validation of standardized tests of academic achievement upon populations not represented in the samples used to standardize the tests is presented, and the results of a field testing of the model are described. The 1973 editions of the Stanford Achievement Test and the Test of Academic Skills were administered to a sample of predominantly West Indian students in the public schools of the Virgin Islands of the United States. Analysis indicated characteristics similar to those...

Social comparison is an important influence on motivation, capability self-evaluations (self-efficacy), and skillful performance. In addition, social comparative information provides a standard against which students can judge their present performance level. Students may experience an initial sense of self-efficacy in attaining a given standard; this sense may in turn enhance motivation. As students observe their progress, self-efficacy is substantiated, and this substantiation helps to...

The concept of the peripheral vision horizon display (PVHD) held promise for significant reduction in workload for the single seat night attack pilot. For this reason it was incorporated in the single seat night attack (SSNA) A-10. The implementation and results of the PVHD on the SSNA A-10 are discussed as well as the SSNA program. The part the PVHD played in the test and the results and conclusions of that effort are also considered.

This paper determines the information required about system recovery to compute the reliability of a class of reconfigurable systems. Upper and lower bounds are derived for these systems. The class consists of those systems that satisfy five assumptions: the components fail independently at a low constant rate, fault occurrence and system reconfiguration are independent processes, the reliability model is semi-Markov, the recovery functions which describe system configuration have small means...

One of the main themes in fluid dynamics at present and in the future is going to be computational fluid dynamics with the primary focus on the determination of drag, flow separation, vortex flows, and unsteady flows. A computation of the flow of a viscous fluid requires an understanding and consideration of the physical aspects of the flow. This is done by identifying the flow regimes and the scales of fluid motion, and the sources of vorticity. Discussions of flow regimes deal with conditions...

The random vortex method (RVM) of Chorin was developed by the recirculating flows. The RVM method models turbulence from first principles, tracking the vorticity and obtaining the interaction of vorticity with the bulk flow field. A computer program was produced called MIMOC, Modeling the Interface Motion of Combustion, which can be used to calculate the reacting flow field behind a rearward facing step. Several comparisons between experimental data and calculations were made. The RVM methood...

The paper discusses the potential benefits of integrating technology, cognitive science, and psychometric theory. It is argued that even though adaptive testing, as currently implemented, is an important achievement, it will be necessary to pay close attention to the psychological foundation of tests to continue advancing the state of the art. Such an effort requires construct validation in the broadest sense, as well as focusing on items and why they differ with respect to psychometric...

Integral Representation for the Viscoelastic Deformation of Ice. Various single integral representations which describe non-linear viscoelastic response are examined with regard to the types of test required to determine the respective kernels. A strain formulation determined by constant uniaxial stress response typical of ice, and its predictions for constant strain-rate response, are reviewed, showing that the latter are sensitive to kernel detail. An alternative stress formulation which is...

Potentially, millimeter wave systems operating near terrain interact strongly with snow cover. The dependence of the millimeter-wave backscatter coefficient on physical snow parameters, such as metamorphic state and free-water content, were explored. The results complement a previous study done on dry slabs removed from snow cover (RADC-TR-81-88). Low-power cw scatterometers at frequencies of 35, 98, and 140 GHz allowed backscatter measurements on in-situ snow at vertical, horizontal, and...

Reasons for not teaching given by the "teaching oriented" students (N=20) included, in order of priority: (1) low...

This report attempts to shed some light on the two issues raised in the title, namely, how many vibration modes does a real structure have, and which of these modes are important? The surprise-free answers to these two questions are, respectively, an infinite number and the first several modes. The author argues that the absurd subspace (all but the first billion modes) is not a strength of continuum modeling, but, in fact, a weakness. Partial differential equations are not real structures,...

The non-reacting flow produced by two confined, co- and/or counter-swirling jets wre measured by means of a two-color laser Doppler velocimeter. These results are compared with earlier experiments and with numerical predictions. It is shown that under both swirl conditions, a closed recirculation zone is created at the combustor center line. This zone is characterized by the presence of a one-cell toroidal vortex, low tangential velocities, high turbulent intensity, and large dissipation rates...
